HORSE-POWER.

SPECZFICATION forming part of Letters Patent No. 399,478, dated March12, 1889.

Application filed November 1, 1888. Serial No. 239,717.

To ZZ whom it 'nz/oy concern.-

lle it known that I, (Ann\"aniomunInnK, a subject ol? the hingotDenmark, residingatlion-up, Kingdom of Denmark, have invented certainnew and useful Improvements in l lorse-Powers, (to r which LettersPatent heretofore were granted to me by the governments of England,dated September 24, 188$, No. 13,777; lirance, dated December 213, 1888,No. 193,680, and Germany, dated January it, 1580, No. 3,642) and I dodeclare the following to be atnll, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in that class of devices known ashorse-powers," and which are provided for the purpose of utilizing thepower of a horse for driving machinery and other similar purposes; andthe object of my invention is to provide a horsepower in which [fewgear-wheels are used for giving the driven wheel a great speed ofrotation, and which also reduces the friction, and is so constructedthat the sudden jolts produced by the irregular movements of the horsedo not al'tfect the driven machinery.

lie invention consists in the combination, with an n 'n'ight spindle, ofa :t'rame mounted to rotate horizontally on the same, shafts in saidframe, a wheel fixed on the outer end of. each shaft and runningon asuitable track, a cogwvheel connected with the innerond of each shaft,and a cog-wheel driven by the cogwheel on the inner ends of the shafts.

The inventimi also consists in tlieeonstru(,' tion and combination oiparts and details, as will be fully described and set forth hereinafter,and pointed. out: in the claims.

In the accompanying drawii'igs, Figure l is a central longitudinalvertical sectional view of my im ni'oved horse-power, parts being brokenout. Fig. 2 is a plan view ot the same, parts bein broken out.

Similar letters of reference indicate correspondin g parts.

The spindle A is secured in a suitable base, K, and on the upper end ofsaid spindle a sleeve, L, is mounted to rotate, on which is fastened atransverse piece, T.

(No model.) Patented in England September Z4,1888,N0. 13,777; in

From each end ol' the transverse piece T two beams, ii, are secured, andare inclined toward each other in horizontal plane, their outer endsbeing secured to a bearing, F. In said bearing F a shaft, A, isjournaled, on the outer end of which a wheel, E, is rigidly mounted. Theinner ends of the shafts A are connected by universal joints with twoopposite beveled cog-wheels, ll 11 mounted loosely on the common bolt orpin n1, passed transversely through the piece T. Raid beveled cog-wheelsll Ilf engage a beveled cogwheel, I), made integral. with a sleeve, M,mounted loosely on the spindle A, said sleeve M being connected with thebeveled cog-wheel C, also mounted loosely on the spindle A, and engagingthe beveled cog-wheel mounted on the horizontal shaft C", connected by auniversal joint with the powcr-transmittin shaft In place of using thecogwheels C bolts and pulleys or other devices maybe used fortransmittingmotion from the sleeve M.

The wheels E run on the circular track C, but may be arranged to run onany other suitable support. A horse is connected with the frame formedby the beams T and 13 at one or bothbearingsdf. Thehorsesarodrivenaroundin a circle, and the wheels E revolve and rotate the beveled cog-wheelsdescribed. The shafts A are connected with the cogavheels by universaljoints for the purpose of avoiding undue bending and twisting strains.\Vhen the horses draw suddenly, the wheelsE slide on their track, andthus no jolts or jars are transmitted to the gear-wheels ll, 11*, andl). by properly weighting thel'rame B, orincreasing the weight of thewheel E, the friction between the wheels and the track can be increased,and thus more power obtained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a horse-power, the combination, with a spindle,of a sleeve on the same, a cross-bar on said sleeve, beams secured tothe ends of said cross-bar and inclined toward each other, bearingssecured to the outer meeting ends of said beam, shafts journaled in saidbearings, and wheels secured on the outer ends of the shaft and runningon a suitable support, cogwheels connected with the inner ends of theshafts, and a cog-Wheel mounted loosely on the spindle and engaged withthe cog-Wheels on the inner ends of the shafts, substantially as setforth.

2. In a horse-power, the combination, with an upright spindle, A, of thesleeve L on the same, the cross-piece T 011 the sleeve L, beams l3,secured to the cross-piece O and to hearings F, the shafts A, journaledin the bearings F, wheels E, fixed on the outer ends of the shafts A,the beveled oog-Avheels ll 11 connected with the inner ends of theshafts A, the transverse bolt on in the cross-bar T, on which bolt onthe Wheels H H are mounted, and the cog- Wheel D, loosely mounted on theSpindle A, substantially as set forth.

In testimony whereof I have affixed my signature in presence of twowitnesses.
